An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices.
When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell.Primary (single-use or "disposable") batteries are used once and discarded, as the electrode materials are irreversibly changed during discharge; a common example is the alkaline battery used for flashlights and a multitude of portable electronic devices. Secondary (rechargeable) batteries can be discharged and recharged multiple times using an applied electric current; the original composition of the electrodes can be restored by reverse current. Examples include the lead-acid batteries used in vehicles and lithium-ion batteries used for portable electronics such as laptops and mobile phones.
Batteries come in many shapes and sizes, from miniature cells used to power hearing aids and wristwatches to, at the largest extreme, huge battery banks the size of rooms that provide standby or emergency power for telephone exchanges and computer data centers.
Batteries have much lower specific energy (energy per unit mass) than common fuels such as gasoline. In automobiles, this is somewhat offset by the higher efficiency of electric motors in converting electrical energy to mechanical work, compared to combustion engines.
Redmi note 9 po model ng device ko. Pinalitan ko siya ng battery due to bootloop, unfortunately if 20% na siya mas madali nang malowbat lalo na kung nag gi-games. I think 1 percent nababawas within 5-10 seconds. Na try ko na po siyang i-calibrate pero dati pa rin. Any alternative solution? Thanks!

so bali kakapalit ko lang ng battery ng phone ko tapos ang problema lang ay nang sshutdown sya mag isa pag 20% na. Pano kaya mafix to? yung battery calibration naman di magamit pag di rooted.
Meron na ba na ka gawa dito?

If meron nakakaalam pa share naman ng knowledge nyo about this.
